LOVED the trailer!
It's tying things together with where we last saw Ahsoka. Whether it's "The Jedi" episode of The Mandalorian (complete with Morgan Elsbeth and her HK droids), or where Ahsoka finally resurfaced during the OT era, after her encounter with Ezra in the world between worlds, and then linking up with Sabine in the REBELS finale. Ahsoka's story around the time of the OT is inextricably linked with the Spectres. And Ahsoka owes a debt to Ezra. I can see that weighing on her.
I am really wondering if Ray Stevenson's character is actually Jorus C'baoth. Especially with the heir to the Empire line. And I loved the Thrawn tease that was in there as well.
I also didn't think I'd be so happy to see Huyang appearance in live action!
